' iv and has forits object to provide, in, a;man-

Be it known that I, SAMMY C. BRAY, citizen of the United fitates,residing at Springfield, in the county; of Greene and State of M ssouri,have invented certain new "and useful Improvements in SewingeMachineNeedle Guards, of which the following s a spec fication,

-This invention relates to needle; guards for usein connection, withsewing machines,

ner as hereinafter set forth, a guard of such class for connection tothe presserf foot of the'machinje and further to'extend into the pathof'and enclose the lower terminal por tion of the needle in a manner toprevent the fingers of .the operator from being injured;

by or to come in contact with the needle during-the operatlon thereof.

-Further objects of the invention are to a'needle-guardforthe purposeset forth which is simple in its construction and arrangement, strong,durable, readily installed I with respectto'the presser footof the mastruction, combination and arrangement of parts as hereinafter morespecifically 'de scribed, andillustrated in the accompanying drawings,wherein is shown an embodiment ofthe invention, but it; is to beunderstood; that changes, variations and modifications; 1 can beresorted to which fall within the,

scope of the claims hereunto appended. v In the drawings wherein likereference characters denote corresponding, parts throughout the severalviews f u Figure 1 isa side elevation of a pressure foot, needle barandneedle, showing the adaptation therewithof a guard lIl accordance withthis invention.

'Figure 2 is a sid elevation of the guard when extended. and furtherillustrating in V dotted 'lines the I guard when -.contracted to permitof the removal ofthe needle when ode-H sired. a I" I r p Figure 3 isatop plan view of the: guard.

Figure 5 is a section onfline 55 -Fig'-' Figure6 is a section on line 66Figure 3. Referring to the drawings'indetail 1 denotes a presser foot,carried on the lower end of a presser foot bar 2. Aneedle bar is in-Kdicatedfatfi and which has, detachably secured to itslower endthe needle4'. The. forego ngjelements are of known construe tion and'areillustrated so that the position of the guard can be shownin operativere lati'on with respect to the-needle 4.,

A needlejguard, in accordance with this inventionco nprises a carrierconstructed of: sheet metal and consisting of a bodyrpo'rtion 5 formedat its inner side With a vertically disposed tubularmember G-for afunction. to be presently referred to." Depending from} the bottom ofthebodyportion 5 and flush with the outer side edge thereof isfasuspenjsion member .of substantial ,width 7 and,

formed of a'verti'cally disposed upper porf tion 7 and a laterallyextending curved lowerjf portion 8 V which terminates in an upstandingvertically disposed tubular member 1 9 having the rear side thereof cutaway toform an opening I 10 hicheXt-ends"from the lower end of: themember 9 and terminates at'a point-removed from the upper end thereofgThe member 9 isformed with an inwardly sideedge of the vertical portion7 of the suspensionmember an arm 12,exteir ding in an opposite directionwith respect to the freefend, isvprovidedcwith inwardly diected'flange13. The arm 12 is furthermore formed with an opening 14. The arm.

curved lower portion 8 of the suspension member .or arm andtl1e*sa1d;'ar m '12, at its 12 isv arranged against; the outer-side or 7rather front side of the presser foot 1 and the tubular member 6 isarranged at the rear side of the presserj foot 1. Extending through theopening ltis a clamping screw 15, which in'connection with theftubiilar,

member .6 'j and the arm 12 detachably secures 1 i the carrier to'thepresser, foot 1 in a manner as shown in Figure ,1 so that thetubularmember 9 will be positioned within the path of the needle 4;; Thetubular 'member 9 forms a stationary section of the guard element of thedevice and such guard element will be presently referred to.

tubular member 9, is of the telescopic type so that when the sectionsthereof a're nested,

, azneedle can be removed and a new one sube stituted.v

. The guard element comprises an upper tu- The guard element, whichincludes the bular sectioniltihaving an inwardly extending annularflange 17 at its lower end, an intermediate tubular section 18whichextends through the flangel'i and has its upper end provided withan outwardly extending annular flange 19 and its lower end with an.

inwardly extending annular flange 19. The flanges 19 and 19 when theguard element is extended abut respectively against theflanges 17 and 9to prevent the separation ofthe=sections of the guard element.The=fiange 9 is formed at and extends outwardly from the upper ofthetubular members 9 which is termed'the lower section of the:guard-element and which extends into the intermediate section 18; Theupper section 161=fricti0nally engages withthe peripheryof theintermediatesection"18- sothat when the upper section 16 is lowered in amanner ashereinafter referred to,- the upper sectlon 16 will carrytheintermediate section {18' therewith and both sections will bearrested by-the curved lower-portion 8 of the suspension member or arm.The -tele. scopic position ofthe sectional guard element, when in nestedposition, is shown in dotted lines 1nv Figure 2. The guard element is.ofa different color from that ofth'e needle to make the latter morediscernible.

A shiftable spring controlled suspension device co-acts" with the uppersection 16 of the guard element, to maintain the latter in extendedposition and when the suspensionv devlce, is shifted manually againstthe action of its controlling spring, the sections of the guard elementcan be shifted to nested position whereby the top edge of the upper sec:tion .16 of the guard element will be positionedbelow'the point of theneedle to per lIlitlOf the latter being removed. Thespring controlledsuspension device consists of a collar'20 carried on the lower end of aspring. controlled suspension rod. 21 which extends up through thetubular member 6 and has mounted on its upper portion a coil control-.

ling spring 22, which is interposed between the top edge ofithe tubular.member 6 and a head. 23provided' at the upper end of the rod 21. Thecollar 20. is connected to the lower .end of therod 21, by an angularlyextending bar 24 which has its outer end fixed to the outer periphery ofthe upper section 16 of the guard element. The bar 24 extends throughthe collar 20 and the lower end of the rod 21. The controlling spring 22normally maintains the collar 20 in abutting engagement with the lowerend of the tubular member 6, under such conditions mainta ning thesections 16 and 18 of the guard element in the position as shown inFigures 1 and 5. If it be desired to nest the sections of the guardelement, relatively to each other, the rod 2lis .shifted to the dottedline position shown in Figure 2 and against the action of itscontrolling spring 22. hen

fall within the scope of the inventionasclaimed.

and connected to v the a section of greatest chameter of said elementfornormally main-g tainingthe latter extended.

2. A needle guard-comprisinga carrier adapted to be connected to thepresser-footof a sewing'machine and having its'lower portion constructedto project into theipath of a needle of the 1nachin e,'an extensible-andcontractile guard element formed of a series of tubular. telescopicsections of different diameters arranged in superposed relation withrespect to the lower portion of the carrier, and a spring controlledsuspension; device slidably supported fromsaid carrier and connectedtothe section of greatest diameter of said element fornormallymaintaining the latter extended, the section of said element of smallestdiameter having a portion of its side slotted and with the slotextendingfrom thebottom of said section;
